Right now, DivX is giving away free serial numbers for DivX Pro (Windows or Mac version).
You need a valid email address to provide during installation.

from website:
"Why Buy DivX Pro for Windows?

Unlike too many things in this world, the answer to that question is pretty simple. If you want to create (awesome, awe-inspiring) DivX videos, you should consider buying DivX Pro for $19.99. If you are primarily interested in just watching (awesome, awe-inspiring) DivX videos, you should download DivX for Windows, and then, if so inclined, use the trial versions of the DivX Converter and DivX Pro Codec to create your own videos and decide if you want to upgrade. (If, on the other hand, you don't know what the word "video" means and your primary interest is, say, traveling the world to compete in professional hot-dog eating contests, then you may be in the wrong place entirely. Not judging, just trying to save everyone some time...) "

thx

Very nice.

Thanks!

Does anyone know if the serial is portable or must be regged on each computer separatedly ?

My A/V processing box is NOT attached to the network directly...

TIA...

Anyone else having trouble registering?
When the key was copied into the box, "register" is still grayed out?

Cool! Thanks.

Thanks OP. Only downside is that it doesn't work with Vista yet. Hopefully an update fixes that.

awesome!
thanks OP!!
